What has become clearer is the fact that an intense cut-off low is expected to develop over the Southern- and Eastern Cape. Cut-off low pressure systems are important weather systems for two reasons:
1. They are capable of stratosphere-troposphere exchange.
2. They are often associated with deep moist convection which can lead to significant amounts of rainfall over short periods of time and therefore flash flooding.
Communities in the Southern Cape and Garden Route area should remain on full alert. Motorists, travelers and members of the public must take note of the high probability of heavy rain, gale force wind (65km/h) and possible flash flooding. Mossel Bay WX will once again bring you the latest updates as the system progresses. It is still to early to say for certain if the system will result in severe weather, however at this stage the system should be observed full time as from tomorrow morning and throughout the rest of the weekend. MSBWX is currently monitoring this system very closely en encourage all it's weather observers to do the same.
MSBWX hereby ask the general public to forward any reports of severe weather conditions and flash flooding to the MSBWX. Use your cellphone, digital camera, email and private weather station etc. in gathering and forwarding information, photos and data to MSBWX. Email observations to MSBWX by clicking HERE.
We also remind our readers that MSBWX also utilize Twitter to keep our readers informed.
